Came across Feedly (http://blog.feedly.com/2013/03/14/google-reader/)
There are developing a tool that allow migrating of Google Reader to their feed reader, Normandy. Good thing is there are apps for Feedly as well.
Anyway, I suggest you to backup your google reader subscription using google takeout (https://www.google.com/takeout/?pli=1#custom:reader)
Details is available in their webpage:
